The graphs below show the minimum, average, and maximum temperatures recorded using a simple car external temperature gauge over several years. The temperatures are therefore neither accurate nor probably statistically significant, but do indicate how many jumpers you might need if you hitch a lift with me.

And although not strictly temperature charts, the next two may be of some interest. The first shows what weather you are most likely to see in each month, and the second shows which month you are most likely to see each type of weather in.
